To all whom. it may r-nll 'llt:

Be it liiHJWH that l. [uvixu Eran. t1. citizen ol the Un .-d States, residing at Wihuingtou. in the county of Newcastle and State of Deluwure, have invented certain now uud useful Improvements in llond-fiitumps: and I do hercb declare the following to ho it full. clear, and exact description of the invention. such as will enable others skilled in the art to which it nppertuins to make and use the same.

This invention relates to certain improvements in hand-stamps.

An object of the invention is the production of an improved stamping-machine {or performing the functions of n hand-stamp and which shall and capable of ready adjustment to bring various combinations of printing characters in line or to the he durable in construction rioting position and which I will avoid certain objections incidental to 3 hand stamps bands carrying rubber type.

The invention consists in certain novel features in construction or in nrran ements or combinations of parts, as more fully set forth hereinafter.

Referring to the accompan 'ing drawings, which show for purposes of exp anation a construction as an example of a desire within the spirit and scope 0 l is a side elevation having ortions broken my invention, Figure 1 having the ordinary flexible tlw iuuiu ironic. 'lhis \'olu -l'rumc comprises the up or cross pluto 7. havin the iii-pending cud plates r ltoiuls urrungcd with their outer vertical lucvs in sliding: engagement with the inner \vl'rirul lures ol' the uprights l and having outwurdlv- |il lt 'iil\} rigid studs or pins J conlim-d to morevcrtit-iillv in theguidcwuys 6. .\t their iuucrhircs those end heads 3* are formed r provided with the olined cirrulur bosses or enlargements Hi.

it is it horizontal ri id metal tube or hullow cylinder arranged between suid bosses with its end edges abutting against the vorticul inner faces of said bosses. The lmsstS are nsuallv of greater tliililititf than the criindex; which is prcforuhly arranged mmtrically with the lmsses. so that the lmssos forth stop-shoulders at the ryliuth-r ends. The cylinder is secured usually by pins ul nmchine-screws l2, pus-sod through the \'okeframe ends and into the cylinder ends. The crlinder is formed with a longitudinal slot i3 throughout the length thereof and usually arranged at the top thereof.

Fl 2 is on end elevation. Fig. 3 is it verticulsection. Fig. 4 is a. plan View of the hottom or face plate of the main frame. Fig. 5 is a detail perspective of in -bar.

n the specifie example illustrated the main frame of the stamp comprises the vertical parallel uprights 1 and the top cross-bar 2, having the central vertical guidewuy or tubular portion 3 usually elongated vertically.

4 is a horizontal face or bottom plate between the u rights 1 and secured to the bottom ed es thereof. This face-plate is longi tudiiml y slotted at 5 to permit the proieetiou 1 ockets in the the universal locktherethrough of the printing characters l l i i i l E and the bosses 10 are vertically slotted or recessed at H at the ends of the slot 13 to receive and guide the ends of a universal locking-bar 15, which extends throughout the length of the tube 11, fitting looselv in the slot 13 thereof. The universal lockinghnr is movable rorliollv of the tube or cylinder and is yieldingiy up icld by springs 16, tending to force the top edge of the bar above the plane of the top surface of the tube. The sprin 's 16 are seated in bosses below the recesses l4 and are usually in the form of expansive coiled sprin 's receiving pins iii, rigid with and dependuw from the ends of the lockinghar 15. The TDClilHg-htll throughout its lougitudinnl outer or top edge is beveled oil in up osite directions to form the outer locking or 'nife edge 18 for the purposes hereinafter set forth.

I mount the printing elements on the tube 11 and between the bosses 10 or yoke ends. The printing elements consist of ii series of inde endent rotnrv parallel, preferably similar, r. isks 19, close y and loosely arranged on said tube and confined thereon between the shoulders formed by the bosses. Each disk is provided with a series of properly spaced or separated printing characters arranged around its periphery. The print-mg charm ters can be out in the metal of the disk or can be separately formed and applied to the edge ICC [ preferably provide each disk \idc ulmllt rw'i-nrv-eight of the preferably j imilar di k l'Iai-h disk is formed with a entral opening f a size to snugly receive said tube and permit the disk to freely turn thereon when released from the lockinglhll. central opening is formed with a series of V- shaped notche or depre sions 20. in munber equal to the number of depressions or Iii-tween the type-faces of the disk and preferably arranged in the radial planes of said spaces between the type-faces. The depressions 20 are formed to receive the tooth or locking edge of the locking-bar which enters a notchof eacluliskmnd thus locks the entire rowot' disks against accidental displacement. Thedisks rotated by hand to present any desired letter or printing-mark at the tinting-point and by means of the series o disks to rovide a row of any desired combination of etters at the printing-point. By reason of the opposite inclined surfaces of the notches '20 and the locking-bar edge the disks can be easily turned in either direction by the fingers against the pressure of the locking bar, which slips in and out of and snaps from notch to notch. The slot in the bottom or face plate of the frame is of a width and length to expose only the row of letters located at the printing osition, and hence said plate serves as a guide in locating the stamp to make the imprint at the desired point or portion of the sheet or article to be stamped, and also said face-plate can serve as a. guide in adjusting each disk to bring the desired letter to the printing-point.

21 represents side )lates secured to the yoke and closing the sides thereof above the row of printing-disks.

tubular vertical stem or handle 2'. is rigid with top plate 7 of the voke and projects looselv through the tubular portion 3 of the main frame and to a point above the same.

23 is a knob or handle secured on and closing the upper end of the tube '34 is a coiled expansive spring arranged in F and compressed between the i the tube 22 knob 23 and a pin or rod 25, passed diametrically through and secured in the tubular por tion 3 and loosel through the tube 22. The

tube .32 is provi ed with longitudinal slots to permit reciprocation of receive said pin and the tube thereon. The front slot is provided at its ends with depressions or sockets 26 to receive the head 27 of the pin 25. The pin '25 passes loosely through the tubular portion The edge of the disk surrounding said i can be separately or independently i and at its rear end is threaded t re ive the nut by adjusting which the head 27 t' the pin 3-) can be drawn into either depre -ioll iii to l ck the yoke at either it d1- pressed or elevation position.

lpreferablyprovide an inking attarhnu-nt. consi ting of a pan or holder 2). for the inkpad 3H. having end arms 5H extending upwardly and outwardly therefrom at an inclination and at their upper ends pivotally I joined bv horizontal screws or pivot-pins to spaces 5 arms 32. rigid with and extending rearwardlv from the uiain-i'ralmuprights l. The inking device is moved to and from inking pu illilll by the links Ji l at their upper end pivotallv to the lower rear portions of the end heads of the yoke and at their lower l'llll\ pivolallv joined to the arms 5H about midwav the lengths of said arms. The end heads bf the yoke are recessed at their outer faces (see H to receive said links 33 between heads and the inner said end faces of the uprights l and permit the swinging movement of said links from about their normal upright positions to a horizontal position. which thev a sume when the voke is forced down to printing position. When the yoke is in its normal elevated positiomin which position it is usually held by the spring 24. the inking device is in its normal posit1onthat is. in inking position-with the trough 2'.) beneath and arranged longitudinally of the row of disks and with the inking-pad ItOdrawn up against the row of type located at the printing position. The printing device is held in this position bv the spring .24 and the yoke through the medium of the links 33.

To operate the hand-stamp to make an impression or imprint. it is merely necessary to press down the knob 23, which causes the reciprocation of the yoke against the tension of the spring 24.nnt1l the printin -type in the printing position have projected through the slot in the face-plate into engagement with the object being printed. This operation can be re eated as many times as desired without 0 ranging the location of or adjustment of the type. As the voke starts on its downward movement the links 33 throw the inking device rearwardly from the disk and it?! the path of downward movement there- The studs 9 are preferably arranged concentric with the tube 11, and said studs guide the yoke in its vertical reciprocation. The type-disks being preferably loosely assembled on the tube can be removed. if found necessary for any purpose, by removing the end screws 12, thereby releasin the tube, so that the same can be removed om the voke with the disks thereon. The yoke itself can be removed from the frame, if found desirable for any purpose, by removing the faceplate from the frame. so that the studs 9 can slide out through the lower open ends of the through said ooves 6 after the in 25 has been removed om the handle-tn e and the knob 23 has been taken 0d.
